I started with 7 eggs in my Brinsea Mini incubator. I candled at day 7 and saw only two spidered eggs with moving embryos. The rest were as follows: clear, clear, clear, darkish (maybe large or broken yolk?), blood ring. I threw out the blood ring egg but left the rest and candled again at 10 days. The previously clear/dark eggs were mostly still clear, but now two are dark. I see no movement in any of them, or spidering. In the clear eggs, the air sac is detached, but not in the darker eggs. Should I chuck all but the two that I see with moving embryos? This is my first hatch, and I'm hoping someone can give me advice so I don't throw away a good egg accidentally! These eggs were shipped to me.
